Abstract
A lighting device has a base, an optic defining an optical chamber, a driver circuit positioned in electrical communication with the base, and a flexible circuit board positioned within the optical chamber along and generally circumscribing a longitudinal axis of the optical chamber and in electrical communication with the driver circuit. The flexible circuit board may comprise a plurality of longitudinal sections. Each longitudinal section may comprise a first inclined section, a second inclined section, and a plurality of light-emitting diodes (LEDs). The first inclined section may be positioned in the direction of the base relative to the second inclined section. The lighting device may further include a longitudinal translation device to translate longitudinally part of the flexible circuit board.
